Artificial insemination is a technique in which sperm is optimized and then injected into the female reproductive tract in a non-coital way to make her conceive. At present, the commonly used technique is the injection of sperm into the female uterine cavity, referred to as IUI. The indications for artificial insemination are: 1, mild oligozoospermia in the male partner; 2, azoospermia in the male partner; 3, difficulty in sexual intercourse; 4, infertility of cervical factors in the female partner; 5, unexplained infertility, and so on. The above groups of people can be considered for artificial insemination, but at least one side of the woman’s fallopian tubes must be clear, and the couple doing artificial insemination must also provide “three certificates”, that is, both sides of the ID card, marriage certificate, and proof of infertility provided by the local family planning management department. Artificial insemination can be categorized into artificial insemination by husband’s semen (AIH) and artificial insemination by donor semen (AID) depending on the source of sperm. The general term artificial insemination usually refers to artificial insemination by husband’s sperm, i.e. AIH, and for patients whose husbands are azoospermic, they can choose to undergo AID, which, according to the national regulations, is currently provided and managed by human sperm banks recognized by the Ministry of Health. Artificial insemination can also be divided into natural cycle artificial insemination and ovulation cycle artificial insemination according to different programs. For patients with normal ovulation, natural cycle insemination is usually chosen, while for patients with ovulation disorders, ovulation induction cycle insemination is usually used.
